How old is this unit? And is this a condenser, air handler or package unit? I am assuming it is rather old and the one printed inside the compartment door is gone or faded. What specifically did you need for wiring?

Hello guys, howdy?
I need help to connect remote summer/ winter switch for UL captive Aire model: (NHMUA 1-6-10 ) make-up air unit.
It is old and used unit and the diagram is missing. Anyone news where I can find the wiring diagram for this unit.
Please help
Thanks

I have a York A/C which has a viable speed fan motor. A room that is the furthest from the air handler is either cold in the winter or hor in the summer. I want to be certain the motor is connected for the highest speed. Where can I find the wiring diagram, or can someone submit it here.
